Cells with cancerous p53 proteins (in red), in the presence of the accompanying protein DNAJA2 (left) and in the presence of its version without a "hairpin" (right). In its presence, the structure of the cancerous proteins is stabilized and they do not stick to each other and therefore remain scattered throughout the cell. In its absence, the cell is not colored red since the proteins form aggregates (red dots) that the cell can recognize and destroy (in blue - the genetic material in the cell nuclei)
